Ring compressor

ABSTRACT

A ring compressor especially suitable for use in installing pistons with rings in removable cylinders of internal combustion engines, pumps and the like. The compressor is made of a cylindrical tube having an inside bore with an inside diameter that is substantially equal to the inside diameter of the sleeve in which a piston is to be installed. The bore of the compressor flares out to a larger diameter at its distal end and has a counterbore that is suitable to receive the end of the cylinder on the engine. The counterbore can rest on the end of the cylinder of the engine to line up the bore of the compressor with the cylinder so that the piston with rings on it slides smoothly into place through the compressor.

1 Claim, 2 Drawing Figures Patented Aug. 28, 1973 L l INVENTOR.

FELIX A. KOMOREK RING COMPRESSOR OBJECTS OF THE INVENTION It is anobject of the invention to provide an improved ring compressor.

Another object of the invention is to provide a ring compressor that issimple in construction, economical to manufacture, and simple andefficient to use.

Another object of the invention is to provide a ring compressorespecially suitable for installing pistons with rings on them intosleeves of removable sleevetype engines.

With the above and other objects in view, the present invention consistsof the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawing and more particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportions, and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention.

GENERAL DESCRIPTION OF THE DRAWINGS FIG. 1 is a top view of the ringcompressor according to the invention.

FIG. 2 is a longitudinal cross sectional view of the ring compressorsupported on a cylinder shown in phantom.

DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular referenceto the drawings, the ring compressor shown has an outside generallycylindrical wall and an inside bore that is counterbored at 11 toreceive the end of the sleeve of an engine. A part of the bore of thecompressor indicated at 12 adjacent the counterbore is cylindrical andapproximately equal to the bore of the engine cylinder. The inside boreof the compressor then flares outwardly at 13 to an amount approximatelyequal to the thickness of the piston ring so that when a pistonindicated at 18 is to be inserted in the cylinder 17 of an engine, thecompressor 10 is rested on the end of the cylinder 17, with the end ofthe cylinder received in the counterbore 11. The piston 18 is thendropped into the top of the compressor and upon movement of the pistonthrough the compressor the piston rings 20 will engage the inside of thebore of the compressor and be compressed so that they move smoothlythrough the cylindrical part 12 of the compressor and into the cylinder17.

The foregoing specification sets forth the invention in its preferredpractical forms but the structure shown is capable of modificationwithin a range of equivalents without departing from the invention whichis to be understood is broadly novel as is commensurate with theappended claims.

The embodiment of the invention in which an exclusive property orprivilege is claimed is defined as follows:

l. A ring compressor comprising a generally cylindrical body having acounterbore in one end adapted to receive the end of a cylinder in whichrings are to be installed,

the inside diameter of said compressor adjacent said counterbore beingcylindrical for a substantial distance and being of substantially equalinside diameter to the diameter of said engine cylinder,

the inside diameter of said compressor increasing gradually toward thedistal end thereof and the distal end of said compressor being flaredwhereby a piston having rings thereon can be inserted in saidcompressor, moved into said cylinder, and the said rings on said pistonbeing compressed uniformly to slide into said cylinder.

1. A ring compressor comprising a generally cylindrical body having acounterbore in one end adapted to receive the end of a cylinder in whichrings are to be installed, THE INSIDE DIAMETER OF SAID COMPRESSORADJACENT SAID COUNTERBORE BEING CYLINDRICAL FOR A SUBSTANTIAL DISTANCEAND BEING OF SUBSTANTIALLY EQUAL INSIDE DIAMETER TO THE DIAMETER OF SAIDENGINE CYLINDER, THE INSIDE DIAMETER OF SAID COMPRESSOR INCREASINGGRADUALLY TOWARD THE DISTAL END THEREOF AND THE DISTAL END OF SAIDCOMPRESSOR BEING FLARED WHEREBY A PISTON HAVING RINGS THEREON CAN BEINSERTED IN SAID COMPRESSOR, MOVED INTO SAID CYLINDER, AND THE SAIDRINGS ON SAID PISTON BEING COMPRESSED UNIFORMLY TO SLIDE INTO SAIDCYLINDER.
